If ( , ) are the roots of the equation ( ax ^2+ bx + c =0 ), then the roots of the equation ( ax ^2+ bx ( x +1)+ c ( x +1)^2=0 ) are
Options
- A( -1, -1 )
- B( +1, +1 )
- C( -1 , -1 )
- D( 1- , 1- )
Correct answer
D. ( 1- , 1- )
Step-by-step solution
The second equation can be rewritten as (a ( x x+1 )^2+b ( x x+1 )+c=0 ) and hence its roots correspond to ( x x +1 = ) and ( x x+1 = ). Hence (x= 1- ) and ( 1- ).
